39. Computer Vision Nearby Injection, het toevoegen van bekende Top10 soorten uit de omgeving

By Kueda
Let op de Nearby Injection en recnete forum posts

Blijkbaar wordt de TOP100 gebruikt
https://forum.inaturalist.org/t/identification-quality-on-inaturalist/7507

I gave a talk on data quality on iNaturalist at the Southern California Botanists 2019 symposium recently, and I figured some of the slides and findings I summarized would be interesting to everyone, so here goes.

Accuracy of Identifications in Research Grade Observations

Some of you may recall we performed a relatively ad hoc experiment to determine how accurate identifications really are. Scott posted some of his findings from that experiment in blog posts (here and here), but I wanted to summarize them for myself, with a focus on how accurate “RG” observations are, which here I’m defining as obs that had a species-level Community Taxon when the expert encountered them. Here’s my slide summarizing the experiment:

And yes, https://github.com/kueda/inaturalist-identification-quality-experiment/blob/master/identification-quality-experiment.ipynb does contain my code and data in case anyone wants to check my work or ask more questions of this dataset.

So again, looking only at expert identifications where the observation already had a community opinion about a species-level taxon, here’s how accuracy breaks down for everything and by iconic taxon:



Some definitions
  • accurate: identifications where the taxon the expert suggested was the same as the existing observation taxon or a descendant of it
  • inaccurate: identifications where the taxon the expert suggested was not same as the existing observation taxon and was also not a descendant or ancestor of that taxon
  • too specific: identifications where the taxon the expert suggested was an ancestor of the observation taxon
  • imprecise: identifications where the taxon the expert suggested was a descendant of the observation taxon
Close readers may already notice a problem here: my filter for “RG” observation is based on whether or not we think the observation had a Community Taxon at species level at the time of the identifications, while my definitions of accuracy are based on the observation taxon. Unfortunately, while we do record what the observation taxon was at the time an identification gets added, we don’t record what the community taxon, so we can’t really differentiate between RG obs and obs that would be RG if the observer hadn’t opted out of the Community Taxon. I’m assuming those cases are relatively rare in this analysis. Anyway, my main conclusions here are that
  • about 85% of Research Grade observations were accurately identified in this experiment
  • accuracy varies considerably by taxon, from 91% accurate in birds to 65% accurate in insects

In addition to the issues I already raised, there were some serious problems here:



Since I was presenting to a bunch of Southern California botanists, I figured I’d try repeating the analysis assuming some folks in the audience were infallible experts, so I exported identifications by jrebman, naomibot, and keirmorse (all SoCal botanists I trust) and made the same chart:



jrebman has WAY more IDs in this dataset than either of the other two botanists, and he’s added way more identifications than were present in the 2017 Identification Quality Experiment. I’m not sure if he’s infallible, but he’s a well-established systematic botanist at the San Diego Natural History Museum, so he’s probably as close to an infallible identifier as we can get.

Anyway, note that we’re a good 8-9 percentage points more accurate here. Maybe this is due to a bigger sample, maybe this is due to Jon’s relatively unbiased approach to identifying (he’s not looking for Needs ID records or incorrectly identified records, he just IDs all plants within his regions of interest, namely San Diego County and the Baja peninsula), maybe this pool of observations has more accurate identifiers than observations as a whole, maybe people are more interested in observing easy-to-identify plants in this set of parameters (doubtful). Anyway, I find it interesting.

That’s it for identification accuracy. If you know of papers on this or other analyses, please include links in the comments!

Accuracy of Automated Suggestions

I also wanted to address what we know about how accurate our automated suggestions are (aka vision results, aka “the AI”). First, it helps to know some basics about where these suggestions come from. Here’s a schematic:

The model is a statistical model that accepts a photo as input and outputs a ranked list of iNaturalist taxa. We train the model on photos and taxa from iNaturalist observations, so the way it ranks that list of output taxa is based on what it’s learned about what visual attributes are present in images labeled as different taxa. That’s a gross over-simplification, of course, but hopefully adequate for now.

The suggestions you see, however, are actually a combination of vision model results and nearby observation frequencies. To get those nearby observations, we try to find a common ancestor among the top N model results (N varies with each new model, but in this figure N = 3). Then we look up observations of that common ancestor within 100km of the photo being tested. If there are observations of taxa in those results that weren’t in the vision results, we inject them into the final results. We also re-order suggestions based on their taxon frequencies.

So with that summary in mind, here’s some data on how accurate we think different parts of this process are.

Model Accuracy (Vision only)



There are a lot of ways to test this, but here we’re using photos of taxa the model trained on exported at the time of training but not included in that training as inputs, and “accuracy” is how often the model recommends the right taxon for those photos as the top result. We’ve broken that down by iconic taxon and by number of training images. I believe the actual data points here are taxa and not photos, but Alex can correct me on that if I’m wrong.

So main conclusions here are

  1. Median accuracy is between 70 and 85% for taxa the model knows about
  2. Accuracy varies widely within iconic taxa, and somewhat between iconic taxa
  3. Number of training images makes a difference (generally more the better, with diminishing returns)

Overall Accuracy (Vision + Nearby Obs)


This chart takes some time to understand, but it’s the results of tests we perform on the whole system, varying by method of defining accuracy (top1, top10, etc) and common ancestor calculation parameters (what top YY results are we looking at for determining a common ancestor, what combined vision score threshold do we accept for a common ancestor). My main conclusions here are
  1. The common ancestor, i.e. what you see as “We’re pretty sure it’s in this genus,” is very accurate, like in the 95% range
  2. Top1 accuracy is only about 64% when we include taxa the model doesn’t know about. That surprised me b/c anecdotally it seems higher, but keep in mind this test set includes photos of taxa the model doesn’t know about (i.e. it cannot recommend the right taxon for those photos), and I’m biased toward seeing common stuff the model knows about in California
  3. Nearby observation injection helps a lot, like 10 percentage points in general

Conclusions

  1. Accuracy is complicated and difficult to measure
  2. What little we know suggests iNat RG observations are correctly identified at least 85% of the time
  3. Vision suggestions are 60-80% accurate, depending on how you define “accurate,” but more like 95% if you only accept the “we’re pretty sure” suggestions

Hope that was interesting! Another conclusion was that I’m a crappy data scientist and I need to get more practice using iPython notebooks and the whole Python data science stack.

. . Can you spare a moment before you click away? iNaturalist is a not-for-profit initiative making a global impact on biodiversity by connecting people to nature with technology. This year alone, 1 million people have contributed observations to iNaturalist, but only 0.24% have donated to support the operations that keep iNaturalist running. Thank you to the 0.24% of the community who are donors! When you donate to iNaturalist, we don’t send you any paper mail (or even ask for your address), we don’t share your email with other organizations, and we put it all back to growing and sustaining this vibrant virtual community. We know not everyone can contribute financially, but if iNaturalist has brightened your life this year, here’s what your gift can do: -$13 stores 10,000 observation photos for a year -$28 sends one day’s worth of email updates -$112 stores 1 million observation photos for 1 month -$333 keeps iNat servers running for 24 hours Can you help?"

HTML is still supported but only a few tags are allowed. is not allowed as it seems but you can use for the same effect. Or you could use Markdown which is also supported as explained in this post:
https://www.inaturalist.org/posts/38475-less-agreeable-observations-more-agreeable-text-formatting 2
The markdown for italics would be text in italics.
It ain’t necessarily so. It depends on whether the text is being read by a visual browser, a screen reader or other agent (such as a search engine).

https://stackoverflow.com/questions/271743/whats-the-difference-between-b-and-strong-i-and-em
Alright then, for screen readers is better defined. So it is actually preferable. Otherwise they should be rendered the same.
Since when is it no longer allowed? It worked just fine until recently and it’s still listed as acceptable text formatting code here: https://forum.inaturalist.org/t/useful-html-tags-for-inaturalist-comments-and-other-text-wiki/6198

Actually, not quite right. In markdown, the asterisk is used to delimit “emphasis” NOT “italics”, so it is equivalent to html . This may be getting a bit pedantic, but is not guaranteed to render as italics (although it usually does). When we are writing comments with latin binomials, those really should be rendered as italics, not just emphasis, so the tag is more appropriate than the markdown asterisk. (That said, I have started using the markdown * in my comments, just because it’s easier.)

Determinatie Sleutel Mossen boek

Veel foto’s in het boek Mosses of Europe van M. Lüth zijn online te zien via deze link: http://www.milueth.de/Moose/#Bildatlas.
http://www.milueth.de/Moose/Bildatlas/atlas%20engl.htm

Overigens staan in die boeken wel veenmossen maar geen levermossen. Om te determineren zijn ze ook niet goed geschikt vind ik.

i guess “easy” is in the eye of the beholder, but you might be interested in some things i mentioned here: https://forum.inaturalist.org/t/species-or-color-search-on-photos/17611/4 1. this thread may also be of interest: https://forum.inaturalist.org/t/how-to-download-taxa/3542 1. if you search the forum for computer vision training or other related keywords, you may also find other discussions that might be relevant.

This research group has some papers on the subject. https://vision.cornell.edu/se3/projects/visipedia/ 3

This is a simpler approach (that could potentially be extrapolated to your bird species) that would be easier for a first machine learning project. https://towardsdatascience.com/image-classifier-cats-vs-dogs-with-convolutional-neural-networks-cnns-and-google-colabs-4e9af21ae7a8 2

43. Look for location in more than 1 picture

  1. Tap the green plus icon, tap “Choose Image,” choose one photo, then tap the camera icon to add more photos
  2. Tap the green plus icon, tap “Choose Image” and long-press to choose multiple photos at once
  3. Tap the green plus icon, tap “No Photo” and tap the camera icon to add photos, manually changing all the other settings
  4. Find a photo in your photos or gallery app and share the photo with iNaturalist, then tap the camera icon to add more photos
  5. Long-press to select multiple photos in your photos or gallery app to share multiple photos as a single observation in iNaturalist
  6. Something else?
    What I’m seeing is that long-pressing in the photos app to share multiple photos with iNat as a single observation currently does what you’re asking for, i.e. it consistently imports coordinates from one of the photos even if another doesn’t have coordinates. Strangely, choosing multiple photos from within the iNat app does not have that effect. If we made both of these behave the same (i.e. we always get coordinates when we can), would that solve your issue, @erininmd?

** Not importing coordinates (or any other metadata) ** when tapping the photos icon on the observation edit screen to add additional photos is intentional. I think we may have done that at some point and it was extremely jarring. Actually I think what we did was prompt you whether or not you wanted to use the metadata from a new photo you were importing and most people found that insanely confusing (I kind of liked it).

I’m not entirely convinced @pisum’s solution of choosing which photo to import coordinates from solves a problem a lot of people are having. I could imagine it being useful in situations where the coordinates are way off on the first photo you took but much better on the last, but that seems like a distant edge case. Just my opinion, though. Could be interesting to show the coordinates from all photos on the location chooser just so you can change the coordinates if the app got coordinates from one bad egg.
